ECQ-B1H333JF3

The Panasonic ECQ-B1H333JF3 is a polyester film capacitor from the ECQB(F) series, designed for general-purpose applications requiring stable capacitance and low losses. It offers a capacitance of 0.033 µF with a tolerance of ±5% and a rated DC voltage of 50 V. The dissipation factor is ≤0.8% at 20°C and 1 kHz, and insulation resistance is at least 30000 MΩ. The capacitor operates over a temperature range of -40°C to +105°C, with voltage derating of 2.5%/°C above 85°C.

Mechanically, the part features a radial through-hole package with a lead spacing of 5.00 mm. Dimensions are 7.50 mm length, 3.50 mm width, and 7.50 mm height. Termination is via PC pins. The capacitor is supplied in bulk packaging with 100 pieces per bag. It is RoHS compliant (unverified), with declared MSL 1 and REACH unaffected (both low confidence).

Typical applications include coupling, decoupling, and filter circuits in consumer electronics, power supplies, and industrial equipment. The non-inductive construction ensures excellent high-frequency performance. For design consideration, derate voltage at elevated temperatures and verify compliance documentation if required.
