JS-12-K Frequently Asked Questions (FAQ)

  • The recommended PCB layout and land pattern for the JS-12-K relay can be found in the FUJITSU Limited application note or by contacting their technical support. A general guideline is to follow the IPC-7351 standard for land pattern design.

  • To ensure reliable switching performance in high-vibration or high-shock environments, consider using a relay socket or a relay with a built-in shock and vibration resistance feature. Additionally, ensure proper PCB mounting and secure the relay to the PCB using a suitable adhesive or mechanical fastening method.

  • The recommended operating temperature range for the JS-12-K relay is -40°C to 85°C. However, it's essential to note that the relay's performance and lifespan may be affected by extreme temperatures. Consult the datasheet or contact FUJITSU Limited for more information.

  • The JS-12-K relay is not designed for use in high-humidity environments. If you need to operate the relay in a humid environment, consider using a relay with a moisture-resistant coating or a conformal coating on the PCB. Consult FUJITSU Limited for more information.

  • The recommended derating curve for the JS-12-K relay can be found in the datasheet or by contacting FUJITSU Limited. A general guideline is to derate the relay's current-carrying capacity by 1.5-2% per degree Celsius above 40°C.
