Category: Electronics, Passive Filters, Spectrum Controls Inc

Spectrum Control Inc presents their range of Hermetically Sealed Threaded Case Filters specifically designed for a variety of applications requiring minimized interference from external electromagnetic noise. These filters are particularly noted for their high performance characterized by their robust hermetic seal and threaded case design. The datasheet details multiple product variants within this category, each with unique specifications to meet diverse requirements.

Product Specifications

The datasheet introduces several models of the 690 0 Pi Circuit filters with varying rated voltages, minimum direct current resistance (DCR), capacitance (Cap max), and minimum insertion loss measured at different frequencies. For example, the part number 51-321-322 offers a rated voltage of 750 VDC and 700 VAC with a maximum DCR of 0.21 Ohms, while maintaining an insertion loss from 35 dB at 30 MHz to 70 dB at 70 GHz. Meanwhile, the 51-321-319 variant handles a rated voltage of 450 VDC and 240 VAC and offers different electrical characteristics such as a Cap max of 5.00 MF and a yet lower minimum insertion loss starting from 30 dB at 60 Hz.

MIL Specifications and DSCC Products

Certain models within this datasheet also meet MIL specifications. For instance, part number 51-321-312 is MIL-qualified under M15733 and features a 200 rated voltage for both VDC and VAC. Varying models under this specification present different insertion loss values, with some reaching up to 80 dB at 80 GHz. Additionally, the DSCC 84084 product line such as the 51-321-398 boasts a robust rated voltage of 400 VDC and VAC, with insertion losses ranging from 27 dB at 30 MHz to an impressive 80 dB at 80 GHz.
