Miniature Signal Relays EA2/EB2 Overview Applications The KEMET EA2/EB2 miniature signal relays offer a compact case size in a flat package. Minimal board space is consumed with either a through-hole or surface mount configuration. These relays are recognized by UL and CSA, while also being compliant with Part 68 of the FCC’s 1,500 V surge capacity. • Electronic switching systems • PBX • Terminal equipment • Telephone systems Benefits • Low power consumption (< 200 mW) • Compact and lightweight • Low magnetic interference • Breakdown voltage: 1,000 VAC (1,500 VAC surge), FCC Part 68 compliant • Tube or embossed tape and reel packaging • UL recognized (E73266) and CSA certified (LR46266) • Surface mount and through-hole options Part Number System EB2- 3 S NU -L Series Coil Voltage Latch Type Lead Type Packaging Blank = Non-latch type S = Single coil latch type T = Double coil latch type NU = Standard Blank = Tube -L = Embossed tape on reel EA2- = Through-hole mount EB2- = Surface mount 3 = 3 VDC 4.5 = 4.5 VDC 5 = 5 VDC 12 = 12 VDC 24 = 24 VDC Built Into Tomorrow © KEMET Electronics Corporation • KEMET Tower • One East Broward Boulevard Fort Lauderdale, FL 33301 USA • 954-766-2800 • www.kemet.com R7001_EA2_EB2 • 12/7/2020 1 Miniature Signal Relays – EA2/EB2 Dimensions – Millimeters EA2 Series B Maximum D Maximum H Maximum 0.33 0.5 0.25 K P2 P1 General tolerance: ±0.2 EB2 Series D Maximum B Maximum H Maximum 0.5 0.25 K P1 P2 General tolerance: ±0.2 11.5 Series D H B P1 P2 K EA2 (NU) EB2 14.2 14.3 5.4 7.5 9.2 9.3 2.54 2.54 7.62 7.62 3.5 1.35 © KEMET Electronics Corporation • KEMET Tower • One East Broward Boulevard Fort Lauderdale, FL 33301 USA • 954-766-2800 • www.kemet.com R7001_EA2_EB2 • 12/7/2020 2 Miniature Signal Relays – EA2/EB2 Pin Configurations Bottom view Single coil latch type (Reset position) Non-latch type (Non-energized position) 3 4 5 1 + - 10 9 8 7 6 2 3 4 Set coil 5 1 +SR - + 10 9 8 7 6 Direction mark 2 Direction mark Direction mark 1 Double coil latch type (Reset position) S: Coil polarity for Set R: Coil polarity for Reset 2 3 4 5 ＋ － ＋ － 10 9 8 7 Reset coil 6 Safety Standards and Ratings Certification Body 1 Mark Specification File Number UL UL Recognized (UL508)1 E73266 CSA CSA Certified (CSA 22.2 #14) LR46266 Rating 30 VDC, 1 A (resistive) 110 VDC, 0.3 A (resistive) 125 VAC, 0.5 A (resistive) Spacing: UL114, UL478 Environmental Compliance All KEMET relays are RoHS Compliant. © KEMET Electronics Corporation • KEMET Tower • One East Broward Boulevard Fort Lauderdale, FL 33301 USA • 954-766-2800 • www.kemet.com R7001_EA2_EB2 • 12/7/2020 3 Miniature Signal Relays – EA2/EB2 Table 1 – Ratings & Part Number Reference Part Number Nominal Coil Voltage (VDC) Lead Type Packaging EA2-3(1)NU EA2-4.5(1)NU EA2-5(1)NU EA2-12(1)NU EA2-24(1)NU EB2-3(1)NU EB2-4.5(1)NU EB2-5(1)NU EB2-12(1)NU EB2-24(1)NU EB2-3(1)NU-L EB2-4.5(1)NU-L EB2-5(1)NU-L EB2-12(1)NU-L EB2-24(1)NU-L 3 4.5 5 12 24 3 4.5 5 12 24 3 4.5 5 12 24 Radial Radial Radial Radial Radial Surface Mount Surface Mount Surface Mount Surface Mount Surface Mount Surface Mount Surface Mount Surface Mount Surface Mount Surface Mount Tube Tube Tube Tube Tube Tube Tube Tube Tube Tube Tape on Reel Tape on Reel Tape on Reel Tape on Reel Tape on Reel (1) To complete KEMET part number, leave blank for Non-latch, insert S for Single coil, or T for Double coil.
