Premier Farnell, The Development Distributor, now stocks KC-LINK Surface Mount Capacitors from KEMET, manufacturers of advanced capacitors and components.

KEMET’s KC-LINK surface mount capacitors are designed to meet the growing demand for fast switching semiconductors that operate at a higher voltage, temperature and frequency. With an operating temperature of up to 150°C, these capacitors can be mounted close to fast switching semiconductors at very high power density applications, which require minimal cooling.

KEMET utilizes a proprietary C0G/NPO base metal electrode dielectric system, making the capacitors well suited for power converters, inverters, snubbers and resonators, where high efficiency is a primary concern. With extremely low effective series resistance (ESR) and very low thermal resistance, KC-LINK capacitors can operate at very high ripple currents with no change in capacitance versus DC voltage and negligible change in capacitance versus temperature.

The KC-Link C0G dielectric technology also provides high mechanical robustness compared to other dielectric technologies, allowing the capacitor to be mounted without the use of lead frames. This provides extremely low effective series inductance (ESL) that increases the operating frequency range, allowing further miniaturization.

Other benefits include an operating temperature range of −55°C to +150°C, high frequency operation (>10 MHz), no piezoelectric noise and the capacitors are also RoHS Pb-free. Automotive grade devices are also available to meet the demanding Automotive Electronics Council’s AEC–Q200 qualification requirements.

Typical applications include:

• Wide bandgap (WBG), silicon carbide (SiC) and gallium nitride (GaN) systems

• Hybrid electrical vehicles (drive systems, charging)

• Photovoltaic systems

• Power conversion

• Inverters

• DC link

• LLC resonators

KEMET KC-LINK surface mount capacitors are now available to buy from Farnell element14 in Europe and Newark element14 in North America.

AEC-Q200 qualified passives have been designed for automotive electronics applications where reliability and stability are required in challenging conditions of high temperature, temperature changes, pressure resistance, humidity and mechanical stress.

These components meet the stringent AEC standards for operating in harsh automotive environments, and are also suited for use in other electronics applications such as wearables, medical, industrial equipment, communications and Internet of Things.

The new ranges include:

• The Vishay IHLD series of low-profile, high current dual inductors in 3232 and 4032 package sizes, offering critical board space saving by combining two inductors in one 9.75mm by 9.14mm package that is optimized for automotive and commercial class D amplifier circuits.
• The FKS Series from Panasonic features increased capacitance, space saving in the same can size and the option of vibration-proofing for automotive applications. The FKS series of aluminum electrolytic capacitors, comprising 25 new part numbers, is available in voltage classes between 6.3V and 50V and capacitance ranging from 33µF to 1800µF in SMD can sizes from 4x5.8mm to 10x10.2mm.
• The newest Radial Lead Type Monolithic Ceramic Capacitor RH Series from Murata is suitable for ECU management where EMI noise and motor surge protection is required. The Murata RH capacitor series provides resistance to solvents and excellent mechanical shock while operating under high temperature conditions of maximum 150°C.
• Kemet’s ultra-low ESR T598 high humidity-high temperature Polymer Electrolytic capacitor delivers higher capacitance and ESR stability for 1,000 hours with 85°C-85% RH load. The T598 Organic Capacitor (KO-CAP) combines the low ESR of ceramic, the high capacitance of electrolytic and volumetric efficiency of tantalum into a single SMD package.
• The Bourns CST0612 series 4-Terminal Current Sense Resistor comes in a 0612 package that offers low resistance values of 0.5 mΩ and handles a maximum power rating up to 1 W. The CST0612 series’ metal alloy current sensing element allows for low thermal Electromotive Force (EMF) and Temperature Coefficient of Resistance (TCR).
• The AVX Glass Encapsulated TransGuard® VGAS Series Multilayer Varistors offer high reliability SMD case sizes from 1206 to 2220 with working voltage from 16 to 65 Vdc for bi-directional overvoltage protection, with the added advantages of greater current and energy handling capabilities, quick turn-on time and EMI/RFI attenuation in off-state mode.

Over 43,000 industry-leading AEC-Q200 passive components, compliant with the global standard for stress resistance for passive electronic components intended for use within the automotive industry, are in stock for same day dispatch. AEC-Q200 qualified passives are suited for use in electronics applications where safety and protection standards are required in engine management, drive-trains, in-vehicle comfort and infotainment, available at http://www.newark.com/passive-components

AEC-Q200 passives from Bourns, Murata, Kemet and more are available from Newark element14 in North America.

element14 has announced it is now stocking two new high-performance metalized impregnated paper series film capacitors from KEMET: the P278, Class X1, 480 VAC and the P295, Class Y1, 500 VAC.

Used primarily for electronic design engineers, these paper capacitors are the best EMI capacitors in terms of safety, reliability, overvoltage and transient handling, self-healing capability and long-term connection to the mains. They have high resistance to ionization and are more stable than any other dielectric available on the market.

The new capacitors are ideal for industrial use with pumps circulators or special high-reliability power supplies. They’re constructed of multilayer metalized paper encapsulated and impregnated in self-extinguishing material meeting the requirements of UL 94 V-0.

Typical applications for the P278 Series include worldwide use as an electromagnetic interference suppressor in all X1 and across-the-line applications. Typical applications for the P295 Series include safety capacitors for bridging of double or reinforced insulation applications requiring voltage test up to 4,000 VAC at 60 seconds. P295 Series capacitors can be left in place during this test.

Priced as low as $.58 and available with next day delivery, the KEMET P278, Class X1, 480 VAC and P295, Class Y1, 500 VAC high-performance metalized impregnated paper series film capacitors are available from Newark element14 in North America, Farnell element14 in Europe and element14 in APAC.
