Datasheet
## 5500 Series/High Voltage Reed Relays ## High Voltage Reed Relays The 5500 Series High Voltage Reed Relays are ideally suited to the needs of Instrumentation, Industrial Process Controls and General Purpose requirements. The specification tables allow you to select the appropriate relay for your particular application. Applications include medical and hipot test instruments, and cable test equipment. If your requirements differ, please consult your local representative or Coto’s Factory. ## 5500 Series Features High Dielectric Strength - 10,000 Volts isolation across contacts High Contact Rating - 200 Watts Hermetically sealed Tungsten contacts for long life Magnetic Shield standard Custom lead terminations and packages available **==> picture [160 x 11] intentionally omitted <==** **----- Start of picture text -----**<br> Dimensions in Inches (Millimeters)<br>**----- End of picture text -----**<br> **==> picture [67 x 9] intentionally omitted <==** **----- Start of picture text -----**<br> Bottom View<br>**----- End of picture text -----**<br> 18 COTO TECHNOLOGY (USA) Tel: (401) 943-2686 / Fax (401) 942-0920 (Europe) o Tel: +31-45-5439343 / Fax +31-45-5427216 ## 5500 Series/High Voltage Reed Relays **==> picture [3 x 4] intentionally omitted <==** **----- Start of picture text -----**<br> 3<br>**----- End of picture text -----**<br> Top View: Grid = .1"x.1" (2.54mm x 2.54mm) 5501, 5503 5502, 5504 ## Notes: - 1Consult factory for life expectancy at other switching loads. 2This relay contains a bias magnet. Correct coil polarity must be observed. Models 5502 and 5504 susceptible to magnetic interaction due to bias internal magnet. 3Consists of 56V Zener diode and 1N4148 diode in series, connected in parallel with coil. ## Environmental Ratings Storage Temp: -35°C to[+] 100°C Operating Temp: -20°C to[+] 85°C Solder Temp: 270°C max; 10 sec. max The operate and release voltage and the coil resistance are specified at 25°C. These values vary by approximately 0.4% / °C as the ambient temperature varies.

When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
