DatasheetCITEL BM surge arresters are 3-electrode gas discharge tubes designed in ceramic technology and created to protect telecommunication or computer equipment,
The reduced size of the BM series enables the implementation in limited space applications (small connector blocks...), SMD mounting (BM CMS type) or PCB mounting (with lead termination : BMS). BM could be provide with external fail-safe mechanism (BMC type) and is available in several DC sparkover voltages.
