Installation Guidelines

• Observe correct polarity; the negative lead is marked on the case.


• Ensure adequate clearance from high‑temperature components to maintain rated lifespan.


• Use appropriate soldering temperature and time to avoid damage to the electrolyte.


• Verify that the circuit voltage does not exceed 400 V DC under normal operating conditions.


• For high‑frequency applications, keep lead length as short as possible to reduce parasitic inductance.
