Filtered Connector Express – Spectrum Control + Richardson RFPD

Spectrum Control connectors deliver high performance and flexibility in a single circular package. With prototypes or production units in as little as 12 weeks and zero NRE, speed meets reliability. Advanced EMI filtering, soldered construction, and rugged aluminum shells ensure durability for the toughest environments.

Configure Your Custom Connector

Select your connector, choose a surface finish (Nickel or Olive Drab Cadmium), and pick an insert configuration (13-35, 15-35, or 17-35). Set circuit values for each pin, then submit to discuss pricing or get technical help. Custom options may affect cost and lead time.

Filtered Connector Express – Overview

Spectrum Control delivers connectors engineered for ultimate performance and adaptability. Designed to handle mixed signals in a single circular package, these solutions offer unmatched flexibility.

Key Features

  • Configurable connector – with circuits/values for mixed signals in a single circular connector package
  • Quick turnaround – for quick prototyping or production units, from specs to finished products in 12 weeks; no NRE
  • Superior EMI filtering – combination of a planar and substrate filtering for superior performance versus chip-on-board (COB) or chip-in-seal versions
  • Soldered construction – for better high-frequency performance over mechanical designs
  • Large capacitance pin-to pin-ratio range – for consistent performance with power and signal filtering in a single package
  • Aluminum shell – for rugged environmental and/or weight sensitive applications

Quality Assurance

All EMI filtered connectors undergo extensive testing to ensure that all products meet specification requirements. Many tests are performed 100% by computer-controlled test sets, including capacitance, dissipation factor, dielectric withstanding voltage, and Insulation resistance as routine. Others are tested on a sample basis as applicable. Test plans can be configured to specific customer requirements.

Qualification/special testing – Spectrum has a fully qualified test laboratory and can provide additional acceptance testing upon the customer’s request. This could be a one-time qualification exercise or ongoing periodic testing.
