• Miniature shielded package
CASE STYLE: HF1139
Product Overview
SXLP-3+ is a 50Ω lowpass filter fabricated using SMT technology. This lowpass filter covers from DC-3 MHz bandwidth, these units offer good matching within the passband and high rejection. This units uses a miniature high Q
capacitors and wire welded inductors for high reliability. In addition it has repeatable performance across production
lots and consistent performance across temperature.
Key Features
Feature
Advantages
Low frequency and fast roll-off
This is a low frequency filter and this will also attenuate frequencies closed to the passband with
good rejection value of >20 dB.
Good VSWR, 1.2:1 typical in passband
The SXLP-3+ has very good return loss for a low frequency bandwidth and provides good interface
when used with other devices.
Small size, 0.44" x 0.74" x 0.27"
The small surface mount package enables the SXLP-3+ to be used in compact designs.
