Energy Storage Chokes (CSHT)
Series: CSHT – 31
Chokes in vertical version enable space economizing, compact printed circuit board assembly.
Storage chokes are used in switching power supply (switch mode regulators) as intermediate energy storage.
These modem supply units offer big advantages compared with older linear regulators:
Small construction size, low power losses, good efficiency and best no load operation behavior.
In order to achieve these advantages only high quality materials must be used as toroidal core.
CALTRON storage chokes achieve their super qualities above all through the use of the special material Molypermalloy, an 80% nickel-iron compound.
Compared with the iron powder core material the thermal behavior at high switching frequencies(<200 kHz) is excellent. The chokes have an almost constant inductance even with high alternating field modulation and high DC pre-magnetizing current.
The simple construction enables high performance parameters with low heat development and an optimum price/performance ratio.

DEFINITIONS
Definitions
| N | turn ratio or voltage ratio between primary and secondary windings. |
| ∫Udt | voltage-time area (Vμs)
This is the product of impulse height and pulse width measured at half impulse height. |
| tr | Pulse rise time (μs)
This time is measured from 10% ÷ 90% of the pulse height. |
| If | Firing current (A) Max. available pulse current. |
| LP | Primary inductance (mH) Measured as per EN 60938 ( signal 0.1mA, tolerance -30 +50%). |
| CC | Coupling capacity (pF) Measured between primary and secondary winding. Is heavily dependent on the winding structure. |
| UR | Maximum operating voltage (V) |
| UP | Test voltage (kV) Measured between primary and secondary winding Also dependent on the winding structure. Measurement 100% in the final test (up to 3.5 kV AC for 2 seconds). |
| UG | Glow discharge voltage (V) Determines the life expectancy of the IT's in operation with excessive operating voltage. At least 50% higher than the max. operating voltage. |
| Pd | Maximum power loss at 50°C ambient temperature. |
