Malvern, Pa. — Vishay Intertechnology Inc. has released surface-mount aluminum capacitors that combine low impedance for better filtering with high ripple current for higher reliability while offering more process flexibility by meeting the rigorous IPC/JEDEC J-STD-020 soldering standard for severe reflow conditions.
The 146 CTI capacitors offer the most severe reflow soldering profile available in eight case sizes. As polarized aluminum electrolytic capacitors with a non-solid, self-healing electrolyte, the AEC-Q200-qualified devices are suited for filtering, smoothing, buffering, and voltage decoupling applications. Typical end products will include automotive power trains and chassis electronics; industrial drives, automation, and equipment for renewable energy; and SMPS units.
The RoHS-compliant 146 CTI capacitors are charge- and discharge-proof, so there is no peak current limitation. For vibration-proof performance, the devices are offered in 4-pin and 6-pin versions.
- Case sizes (mm): 10x10x10 to 18x18x21
- Capacitance at 100 Hz (µF): 22 to 4,700
- Voltage range (V): 16 to 63
- Impedance (Z) at 100 kHz, 20°C (O): 0.035 to 0.430
- Ripple current at 100 kHz, 125°C (mA): 400 to 1,750
- Temperature range: - 55°C to + 125°C
Pricing: Depends on case size, values, and volume ordered. An example of budget pricing for a 146 CTI 100-µF, 50-V device for U.S. delivery is $0.68 USD per each.
Availability: Samples of the new capacitors are available on request. Production quantities will be available in November 2010, with lead times of eight to 12 weeks.
