Previously, to achieve a 5kV stand-off rating, a larger, non-SIP (Single-in-Line-Package) relay was required. Four of the new 104 5D parts can fit the same PCB area that one larger style occupied, even with sufficient clearance space between adjacent parts.
According to Pickering Electronics this is the first miniature SIP reed relay with a standoff of up to 5kV and up to 1.5kV switching and is intended for where a compact design is essential, as the devices can stack at just 6.35mm.
The Series 104 reed relays are suitable for mixed signal semiconductor testers, cable testing, monitoring photovoltaic efficiency, EVs & charge point testing, mining gas analysis, medical electronics, in-circuit test equipment, and high voltage instrumentation. 5kV devices are available in 1 Form A (SPST N.O), and 5, 12 or 24V coils with optional internal diode protection.
Where extended operating temperature ranges are required, 104HTs are designed to work from -40 °C to +125 °C, or custom versions are available up to +150 °C.
