- The frequency fC is defined as the midpoint between the 3dB frequencies.
- Unless noted otherwise, all measurements are made with the filter installed in the specified test fixture that is connected to a 50 Ω test system with VSWR ≤ 1.2:1.
- The test fixture L and C are adjusted for minimum insertion loss at the filter center frequency, fC.
- Unless noted otherwise, specifications apply over the entire specified operating temperature range.

Engineering review checklist
- Check resistance value, tolerance, temperature coefficient and long-term stability over the operating range.
- Derate continuous power for ambient temperature and verify pulse or surge capability separately.
- Match the land pattern, termination finish and current-sense routing to the exact package option.
Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
