The MA Series of Transient surge suppressors are axial-lead metal oxide varistors (MOVs) for use in a wide variety of board level industrial and commercial electronic equipment. They are intended to protect components and signal/data lines from low energy transients where the small axial lead package is required. The MA Series is offered with standard (S suffix) or tightened (B suffix) clamping voltage. See MA Series Device Ratins and Specifications table for part number and brand information.

The RA Series transient surge suppressors are varistors (MOVs) supplied in a low-profile box that features a precise seating plane to increase mechanical stability for secure circuit-board mounting. This feature makes these devices suitable for industrial applications critical to vibration. Their construction permits operation up to 125°C (ambient) without derating. The RA series are available in voltage ratings up to 275V V M(AC)RMS and energy levels up to 140J. These varistors are used in automotive, motor control, telecommunication, and military applications.

The ZA Series of transient voltage surge suppressors are radial-lead varistors (MOVs) designed for use in the protection of low and medium-voltage circuits and systems. Typical applications include motor control, telecom, automotive systems, solenoid, and power supply circuits to protect circuit board components and maintain data integrity. These devices are available in five model sizes: 5, 7, 10, 14, and 20mm, and feature a wide V DC voltage range of 5.5V to 615V. See ZA Series Device Ratings and Specifications table for part number and brand information.

The CA Series of transient surge suppressors are industrial high-energy disc varistors (MOVs) intended for special applications requiring unique electrical contact or packaging methods provided by the customer. The electrode finish of these devices is solderable and can also be used with pressure contacts. Discs of the same diameter may be stacked. This series of industrial disc varistors are available in three diameter sizes of 32, 40, and 60mm, with disc thicknesses ranging from 1.8mm minimum to 32mm maximum. They offer a wide voltage range of from 130 to 2800 V M(AC)RMS .

The DHB34 Series of transient surge suppressors are industrial highenergy Metal Oxide Varistors (MOVs). They are designed to provide surge suppression in the AC mains outdoor and service entrance environment (distribution panels) of buildings. DHB34 applications also include industrial heavy motors, controls, and power supplies such as used in the oil-drilling, mining, and transportation fields, including HVAC and motor/generator applications. The DHB34 Series provides rigid terminals for through-hole solder mounting on printed circuit boards, thereby eliminating the need for screw mounting. See Ratings and Specifications table for part numbers.Note: Ratings are for each individual element in dual assembly. Average power dissipation of transients not to exceed 2.0W per varistor element (2 varistors per device).

HA Series transient surge suppressors are industrial hgh energy metal-oxide varistors (MOVs). They are designed to provide secondary surge protection in the outdoor and servie entrance environment (distribution panels) of buildings, and also in industrial applications for motor controls and power supplies used in the oil-drilling, mining, and transportation fields. The design of the HA Series of metal oxide varistors provide rigid terminals for screw mounting. Also available in a clipped lead version for through hole board placement or to accommodate soldered leads-designation "HC".
