Description
These new devices have been designed to meet the
increasing demand for surface mounting technology.
This device is used for outdoor or for low power
applications.
The package of the TLMD310. is the P–LCC–2
(equivalent to a size B tantalum capacitor).
It consists of a lead frame which is embedded in a
white thermoplast. The reflector inside this package is
filled up with clear epoxy.
