DDK|DDK Connectors|NIPPON ELECTRONICS BM1 Series SMB Shape Coaxial Connectors is a connector that is the same size as SMA connector by making the BNC connector smaller. Compared with BNC connectors, it can save 50% space. The mounting method is the same as the BNC connector with bayonet locking. No torque management is required for mating, and it is easier to disengage than the SMA connector.

| The general specifications for the electrical performance of this series of products are: | |
| Characteristic impedance: 50Ω | Insulation resistance: DC500V 1000MΩ or above is used |
| Rated voltage: AC500V(r.m.s.) | Contact resistance: below 3mΩ |
| Use temperature range: -40~+85℃ | Voltage constant to wave ratio: 1.2 or less (DC to 3 GHz) |
| Withstanding Voltage : AC1000V(r.m.s.) for 1min. | Below 1.3 (DC ∼ 6 GHz) |
