Vishay Intertechnology has extended the capabilities of its 140 CRH series of surface-mount aluminum capacitors to offer capacitance values and ripple currents. A polarized aluminum electrolytic capacitor with a non-solid, self-healing electrolyte, the 140 CRH is ideally suited for filtering, smoothing, buffering, and voltage decoupling applications in automotive and industrial systems for high ambient temperatures up to 125°C. Offering enhanced performance and reliability, the devices feature a capacitance range of 10μF to 1000μF over a voltage range of 6.3V to 63V, a high ripple current up to 900mA at 100kHz/125°C, and ESR down to 90mΩ at 100kHz. The capacitors are available in five case sizes, ranging from 8mm by 8mm by 10mm to the larger 12.5mm by 12.5mm by 16mm. For high vibration capability, the 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 broad temperature range from -55°C to +125°C. The samples and production quantities of the 140 CRH SMD aluminum capacitors are available now, with lead times of 15 weeks for larger orders.
