Notes from Tables
3. These transformers are verified to operate from -40°C to +85°C.
Contact Pulse Applications Engineering for performance data.
1. Impedance and turns ratios are specified primary:secondary.
(CT=Center Tap).
2. Bandwidth is referenced to midband loss.
Application Notes
A. Bandwidth specifications for CX2040LNL and CX2047LNL are for a
50 Ω system.
D. For additional impedance ratios and frequency ranges, please contact
Pulse Applications Engineering.
B. Materials used in the products are UL94-V0 recognized. Products meet
requirements of IEC 695-2-2 (Needle Flame Test).
E. Pick and place operation: smooth upper surface of device allows
automatic pick and place.
C. CX2038LNL, CX2039LNL, and CX2043LNL transformer configurations
do not provide DC isolation between primary and secondary windings.
F. For availability of lead-free version of this product, please contact Pulse.
