High-Temperature Metallized Polyester Box Capacitors

The Tecate Group introduced its miniature, radial lead TYPE 9245WT Series of metallized polyester (PET) box capacitors. Devices feature the extended temperature range (up to 105 °C) and high voltage capability required by telecom applications, and are constructed in rugged rectangular plastic cases with 5 mm lead spacing. Tecate's 9245WT capacitors are provided in voltages ranging from 50 VDC to 1000 VDC, and in capacitance values from 0.001 µF to 1 µF to further maximize design flexibility. The non-inductively wound RoHS-compliant parts boast exceptional self-healing properties to promote long product life and ensure the utmost in reliability and safety.

Engineered for space-constrained applications in which high temperature is a factor, Tecate's TYPE 9245WT metallized polyester box capacitors are uniquely suitable for blocking, coupling/decoupling, filtering, bypass, energy storage/discharge and arc suppression in wireless and broadband telecom applications. They are equally appropriate for employment in data processing equipment, industrial instrumentation, automatic control systems, and in varied general electronic equipment.

The capacitors feature an extended temperature range of -40 to +105 °C with full rated voltage, and to +120 °C with voltage derating. They are provided in 20 capacitance options ranging from 0.001 µF to 1 µF, and in voltage options of 50/63 VDC, 100 VDC, 250 VDC, 400 VDC, 630 VDC, and 1000 VDC. While all TYPE 9245WT parts feature 5 mm lead spacing, their rectangular plastic cases range in size from 7.2 mm (L) x 2.5 mm (W) x 6.5 mm (H) up to 7.2 mm (L) x 6.0 mm (W) x 11.0 mm (H). Case and epoxy fill meets UL94V0. Capacitance tolerances are ±5%, ±10% and ±20%. Dielectric strength is 1.6 Vr for 2 seconds, and dissipation factor is 1.0% max. at 1 KHz at 25 °C.

Pricing for Tecate's TYPE 9245WT metallized polyester (PET) box capacitors ranges from $0.035 to $0.22 each in quantities of 5,000. Delivery is from 6 to 8 weeks ARO. Samples are immediately available.
