TDK Launches High Impedance Chip Beads
Uniondale, NY — TDK Corporation has launched its MMZ0402EUC series of chip beads, which, according to the company, has the lowest DC resistance for a chip bead of its size. The two new series have respective impedance values of 150 and 180W at 100 MHz, and DC resistance values of 0.62 and 0.69W. This results in a significant reduction in power loss, while at the same time providing noise suppression. The compact IEC 0402 compo-
nents have dimensions of 0.016 x 0.008 x 0.008 in. (0.4 x 0.2 x 0.2 mm) and exhibit impedance that is up to 20 percent higher than TDK’s existing MMZ chip beads. With rated currents of 350 and 300 mA, the new MMZ0402EUC chip beads are suit- able for noise suppression in the power
and signal circuits of smartphones, tablets and other mobile devices. The components can be used in a range of temperatures from –67 to

+257°F (–55 to +125°C). TDK plans to expand the available range of impedance values in the lineup to meet the requirements for a broader
range of mobile device designs. Contact: TDK Corporation of

KEMET Provides High-Temp Bulk Capacitors
Simpsonville, SC — KEMET has launched its KPS-MCC C0G 392°F (200°C) bulk capacitance solution for use in harsh environments. The capacitors were developed by com- bining the company’s proprietary C0G/NPO base metal electrode (BME) dielectric system with durable lead frame technology. These capaci- tors are suitable for demanding high- temperature, high-voltage and high- vibration applications, such as down- hole oil exploration, automotive and hybrid electric vehicles (HEV), defense, and aerospace. The KEMET C0G BME dielectric
Test for gross and fine leaks in as little as 6 minutes.*
system is designed to provide high reli- ability at operating temperatures up to 392°F (200°C), while maintaining high insulation resistance, low ESR and high ripple current capability at high frequencies. This series is built to pro- vide stability with no capacitance change versus DC voltage. A high melting point (HMP) sol-
der for lead attachment enables mul- tiple chips to be stacked in parallel, providing bulk capacitance and mechanical strength. Excellent elec-
trical performance, high reliability, and the robustness of KEMET’s BME C0G dielectric provides a better solution than Class II (X7R/X5R) capacitors above 79.4°F (175°C).
KPS-MCC C0G high-temperature capacitors.
Available in three case sizes, the
KPS-MCC series offers voltages up to 2,000V and capacitance up to 2 µF in a footprint of less than 0.55 in.2 (3.6 cm2). Each case size can be ordered in a straight pin, formed “L” or formed “J” configuration and with a silver- or
solder-coated termination finish. Contact: KEMET Corp., 2835

TT Electronics Expands Metal Foil Chip Resistor Range
Only NorCom optical leak technology detects both gross and fine leaks in hermetically sealed packages, this fast. Instead of using multiple technologies
and processes, you can leak test virtually any type of package with one high-speed system. The NorCom 2020™
series inspects hermetically sealed components to
MIL-STD 883 requirements either in seam seal trays, or when already mounted to circuits boards and assemblies. It automatically rejects failed devices, and reports the leak rate for each part, eliminating “divide and conquer”leak testing.

Perry, OH — TT Electronics has expanded its MFC series of metal foil on ceramic chip resistors with a new 2817 size that can dissipate up to 3W. Suitable for current sensing in the 1 to 30A range, the MFC2817 chip resistors are designed for com- pact power conversion circuits in demanding industrial and medical applications. In addition to power supply and
DC-DC converters, the resistors also meet the current measurement requirements of driver circuits for motors, actuators,
lighting, and
HVAC systems. This growing market for distributed power management and motion control is being chal- lenged to reduce power loss while maintaining accuracy, leading to a demand for lower ohmic values and reduced TCRs. The MFC2817 addresses this
need with values from 3 to 150 mW and a low TCR of ±30 ppm/°C. Metal foil on ceramic technology
offers superior reliability when com- pared with other resistor technolo- gies. Its surge tolerance is better

than thick-film resistors, ensuring improved reliability in the presence of current surges. Also, its self-heat- ing is lower than thick-film or metal- strip types, avoiding hot-spots and
further improving product reliability. Contact: TT Electronics, 3700
