2 Elements Direct Coupling Type

• Center frequency (fo) is available in a range of 450 to 470KHz. The standard tolerance of fo is ±±KHz. ꢀor synthesizers and digital indicators, ±ꢁKHz tolerance is also available.

• The LPZ455JL series, with its two directly coupled elements, has a high degree of selectivity. The series features excellent matching characteristics for IꢀT.
