Operating temperature range of -20 to +70°C
Most UM1/5 modes also available in HC49U/T
Formed leads and jacket SM option available for UM1 and UM5
The filters should NOT be exposed to temperature higher than 150°C
For M series filters, hand solder is required. Use low melting point solder (lower than 160°C typical) on the leads, no more than 3 seconds
Please consult VTC support for the other specifications not listed above.
