MicroCapacitance (MC) SA SIDACtor® Device
These DO-214AA SAMC SIDACtor devices are intended for applications sensitive to load
values. Typically, high speed connections, such as Ethernet, xDSL, and T1/E1, require a
lower capacitance. CO values for the MicroCapacitance device are 40% lower than a
standard SA part.
This SAMC SIDACtor series enables equipment to comply with various regulatory
requirements including GR 1089, ITU K.20, K.21, and K.45, IEC 60950, UL 60950, and TIA-
968-A (formerly known as FCC Part 68).
* “L” in part number indicates RoHS compliance. For non-RoHS compliant device, delete “L” from part number.
For surge ratings, see table below.
General Notes:
• All measurements are made at an ambient temperature of 25 °C. IPP applies to -40 °C through +85 °C temperature range.
• IPP is a repetitive surge rating and is guaranteed for the life of the product.
• Listed SIDACtor devices are bi-directional. All electrical parameters and surge ratings apply to forward and reverse polarities.
• VDRM is measured at IDRM.
• VS is measured at 100 V/µs.
• Special voltage (VS and VDRM) and holding current (IH) requirements are available upon request.
