Malvern, Pa. Vishay Intertechnology, Inc. has extended the capabilities of its 140 CRH series of surface-mount aluminum capacitors to offer very high capacitance values and ripple currents, aimed at automotive and industrial systems.
A polarized aluminum electrolytic capacitor with a non-solid, self-healing electrolyte, the 140 CRH is well-suited for filtering, smoothing, buffering, and voltage decoupling applications in automotive and industrial systems for high ambient temperatures up to 125°C.
The devices feature a capacitance range of 10 F to 1000 F over a voltage range of 6.3 V to 63 V, a high ripple current up to 900 mA at 100 kHz/125°C, and equivalent series resistance (ESR) down to 90 mΩ at 100 kHz. The capacitors are available in five case sizes, ranging from 8 x 8 x 10 mm to 12.5 x 12.5 x 16 mm.
For high vibration capability, 140 CRH capacitors with 12.5-mm diameters are available in 4-pin versions, with 4-pin versions of 10-mm devices available on request. The capacitors feature a long life up to 3000 hours at +125°C. The RoHS-compliant devices are charge- and discharge-proof, so there is no peak current limitation. The capacitors operate over a temperature range from -55°C to +125°C.
Pricing: Ranges from $0.35 to $0.75.
Availability: Samples and production quantities are available now, with lead times of 15 weeks for larger orders.
