WA04P004XBTL

Overview

The WA04P004XBTL is a fixed RF attenuator manufactured by Walsin Technology Corporation. It provides an attenuation value of 4 dB with a tolerance of +/-0.3 dB. The component operates within a frequency range of 0 Hz to 3 GHz and maintains a nominal impedance of 50 Ohms. It features a maximum Voltage Standing Wave Ratio (VSWR) of 1.2 and supports a power handling capacity of 100 mW. The device utilizes ceramic technology and is housed in a 0404 (1010 Metric) convex package. It functions reliably across an operating temperature range from -40°C to +125°C.

Feature Summary
