Procurement Notes

Verify the specific ordering suffix against official TDK documentation to ensure correct electrical ratings. Confirm that the required maximum current and energy specifications align with the target application's peak load requirements. Ensure compliance with RoHS standards if mandated by the end product design.

Selection Notes

Select this component based on the required nominal resistance value and the maximum allowable steady-state current. Evaluate the expected energy dissipation during switching events to ensure it remains below the 500 Joule limit. Consider the operating temperature range to guarantee reliable performance under extreme environmental conditions.
