Active PCB Mount Video Ground Isolator with Field Tilt Corrector  
North Hills’ part number 1121TC has been obsoleted and replaced by the NH16692. The NH16692 is a PCB mountable active device that is 94% smaller and weighs 84% less than the 1121TC. It has a bandwidth of DC to 8 MHz, requires a 5VDC supply and provides over 120 dB of isolation for common mode voltages up to 500Vrms.

PCB Mount Video Tilt Corrector
Blocking capacitors and inductive loads will limit the low-frequency response in a video transmission network.  The result is a field tilt that, if excessive, may ruin sync and picture quality.  The Video Field Tilt Corrector will restore the original waveform with minimal residual tilt.

DTV Humstopper 50 MHz – 900 MHz
The solution for passing any UHF/VHF-based signals, including Digital Television ("DTV"), without degradation, while eliminating any ground loop interference (50-900MHz).

High Frequency Wideband Transformer 5 MHz - 1.2 GHz
Ultra High Frequency 50 ohm to 100 ohm balun provides an easy and straightforward means of measuring circuit characteristics to 1.2 GHz.

Balun Transformers for C.I.S.P.R 17/IEC 1981 Measurements

Balun Transformers for C.I.S.P.R 17/IEC 1981 Measurements
The NH16434 and NH16435 are optimized for C.I.S.P.R 17/IEC measurements

Video Isolation Transformers – Extended Frequency Range 10 Hz to 15 MHz

Video Isolation Transformers – Extended Frequency Range 10 Hz to 15 MHz
DC-isolated "Humstoppers" with an extended frequency range of 10 Hz to 15 MHz for power-line isolation.  Available in 50:50 (model number: 0013CC) and 75:75 (model number: 1113CC) impedances.

Video Isolation Transformers – For Video Feeds with DC Component
The NH16130 removes picture stability problems that have been encountered in the field when video isolation transformers were fed from signal sources that contained a DC component.

New MIL-STD-1553 Data Bus Product

Dual Ratio MIL-STD-1553 Data Bus Interface Surface Mount Transformers
This newly designed interface transformer contains a dual ratio in a single package.  With dimensions of 0.63” x 0.93” x 0.155” and weighing less than 4 grams, this transformer is designed for programs that are weight-sensitive and have limited space and volume for installation.

Space Data Bus Coupler Connector Saver

Space Data Bus Coupler Connector Saver
Connector Savers are used on the original connectors so that they are mated once and left on through the testing until the launch.  This prevents the plating on the connectors from being abraded and peeling off.

In-line Sub-Miniature Data Bus Coupler

In-line Sub-Miniature Data Bus Coupler
Data Bus Couplers for programs that are weight sensitive and have limited space and volume for installation.

Ultra Compact Box Data Bus Coupler

Ultra Compact Box Data Bus Coupler
Utilizing a low profile design and lightweight robust construction, this data bus coupler delivers big advantages with the same superior electrical performance at a fraction of the size.
