RoHS
Description
CH Series transient surge suppressors are small,
met
al-oxide varistors (MOVs) manufactured in leadless
chip form. They are intended for use in a variety of
applications from low voltage DC to off-line board-level
protection. These devices, which have significantly
lower profiles than traditional radial lead varistors,
permit designers to reduce the size and weight and
increase the reliability of their equipment designs.
CH Series varistors are available in a voltage range from
14V to 275V (V
M(AC)RMS
), and energy ratings up to 8J.
See the Littelfuse Multilayer Suppressor Series also.

Device Ratings and Specifications
NOTES:
1. Power dissipation of transients not to exceed 0.25W.
2. Energy rating for impulse duration of 30ms minimum to one half of peak current value.
3. Also rated to withstand 24V for 5 minutes.
4. All Littelfuse CH Series Varistors are recognized under UL file #E320116 as a recognized component.
5. The Typical Capacitance is for reference only
Current, Energy and Power Derating Curve
Continuous power dissipation capability is not an applicable
design requirement f
or a suppressor, unless transients
occur in rapid succession. Under this condition, the
average power dissipation required is simply the energy
(watt-seconds) per pulse times the number of pulses
per second. The power so developed must be within
the specifications shown on the Device Ratings and
Specifications Table for the specific device. Furthermore,
the operating values need to be derated at high tempera
tures as shown in this diagram. Because varistors can only
dissipate a relatively small amount of average power they
are, therefore, not suitable for repetitive applications that
involve substantial amounts of average power dissipation.

NOTE: If pulse ratings are exceeded, a shift of V
N(DC)
(at specified current) of more than +/-10% could result. This type of shift, which normally results in a decrease of V
N(DC)
, may result in
the device not meeting the original published specifications, but it does not prevent the device from continuing to function, and to provide ample protection.
