Ordering / RFQ notes

  • Confirm exact ordering code, coil voltage, contact form and termination style before purchase.
  • Share load voltage/current, load type, duty cycle, ambient temperature and isolation requirement in RFQ.
  • Use the linked PDF datasheet for package drawing, dimensions and final rating limits.
  • For reed relays, keep switching voltage, stand-off/hold-off voltage and dielectric strength separate during selection.
  • Product family context: Standard & Miniature Reed Relay.
Engineering selection notes

Avoid common specification mistakes

These notes keep product pages useful for engineers while avoiding overclaims. Final ratings remain model- and application-specific.

Separate switching, stand-off and dielectric ratingsSwitching voltage is the voltage the relay may open or close under specified load. Stand-off/hold-off and dielectric ratings are withstand tests and should not be treated as hot-switching capability.
Dry reed relays are low-bounce, not universally zero-bounceUse model datasheets for operate time and bounce behavior. Reserve bounce-free language for mercury wetted contacts or explicitly specified designs.
Load type controls lifeCapacitive inrush, inductive energy and hot-switching conditions can reduce contact life. Confirm load type, duty cycle and safety margin through datasheet review and RFQ.

Typical applications

  • Test and measurement equipment
  • Telecom and data-line switching
  • Industrial control boards
  • Medical diagnostic instruments

What to confirm before purchase

  • Voltage, current, load type and safety margin
  • Contact form, coil voltage and drive circuit
  • Mounting, wiring, environmental and compliance requirements
  • Sample validation quantity and production forecast
