SIP SERIES REED RELAYS
SIL4 DSS4 MVS4 MSS4
DESCRIPTION
SRC Devices offers a large selection of molded SIP relays to meet customer applications. The DSS4 was developed several years ago and continues to be the relay of choice for hook switch applications in modems and general purpose applications. The SIL4 is the first of a series of new molded products ideally suited for use in high reliability requirements. Its design centers on a new patent pending process aimed at protecting the hermetically sealed reed switch. When properly protected, the reed switch outperforms most other electromechanical switching devices for operating life (at low signal levels), isolation, low resistance and low operating power. The high performance MVS4 and MSS4 models provide bounce free operation and offer a more durable contact when switching capacitive or inductive loads. Both are capable of switching loads up to 50 watts.
FEATURES
Patent pending process (SIL4) High reliability switching 3V operate option available Quality defect levels <50 PPM (SIL4) Long operating life at low levels ( >1 billion operations) Capable of switching up to 1000V High isolation between input and output (2500V) Optional internal diode & N.C. option High density board mounting Automatic insertion design State-of-the-art capsule designs Epoxy molded single-in-line package FCC68 compatible on MSS4 model
APPLICATIONS
ATE - Functional board testers - Integrated circuit testers - Bare board testers Telecom Matrix requirements Instrumentation Data acquisition
