Non Compensated Chokes (CLTP)
Series: CLTP – 10, 14, 15, 18, 20, 22, 23, 28, 33
Chokes in vertical and Horizontal version enable space economising, compact printed circuit board assembly.
All choke types comply with the guidelines of EN 60938-2.
In combination with suitable capacitors, high quality interference suppression filters against parasite interference influences are achieved. Main application fields are: general purpose filtering of parasite disturbance factors above all with symmetric interferences e.g. in frequency converters, switch mode power supplies, automotive electronics etc.
Frequently they are also used in combination with current compensated interference suppression chokes. Optimum adaptation of core materials and technical design guarantee the best possible compliance with the world-wide high requirements with the smallest volume.
The simple construction enables high performance parameters with the smallest heat development and an optimum price-performance ratio.
Four closed housings are complemented by one version in open structure.

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. |
