Features
1. Perfect for high density surface mount applications since magnetic shield eliminates crosstalk.
2. Highly reliable in wide temperature and humidity range. Superior Q characteristics in wide frequency.
3. Terminal electrode has excellent solder heat resistance.
Applications
1. Prevention of electromagnetic interference to signals on the secondary side of electronic equipment.
