B39921B3718U410 Description

Short technical summary and product information.

The EPCOS B39921B3718U410 is a SAW RF filter designed for short-range device applications, such as remote control receivers. It operates with a center frequency of 916.00 MHz and requires no matching network for operation at 50 Ω.

Key electrical characteristics include a maximum insertion attenuation of 3.0 dB and an amplitude ripple of 0.5 dB within the passband (914.25 ... 917.75 MHz). The filter provides significant attenuation in out-of-band frequencies, with a minimum of 36 dB at 10.00 ... 897.00 MHz.

This component is housed in a compact 3.0 x 3.0 x 1.1 mm surface-mount package (DCC6C) with Ni, gold-plated terminals, making it compatible with lead-free soldering processes. It is AEC-Q200 qualified and considered an Electrostatic Sensitive Device (ESD).

The operable temperature range is -45 ˚C to +125 ˚C, with specifications typically provided at 25 ˚C and across the -40 ˚C to +85 ˚C range. Maximum ratings include a DC voltage of 6 V and source power up to 20 dBm under specific duty cycle conditions.
