3 / 3 page 82 RA REFERENCE DATA 1. High frequency characteristics Sample: ARA200A12 Measuring method: Measured with HP network analyzer (HP8753C). • Insertion loss • Isolation • V.S.W.R. 0.8 1.0 0 0.2 0.6 0.4 0.3 300kHz 0.5GHz 1.0GHz COM-NC COM-NO Frequency 80 100 0 20 30 60 40 300kHz 0.5GHz 1.0GHz COM-NC COM-NO CONTACT sets Frequency 1.1 1.0 1.5 1.4 1.2 1.3 300kHz 0.5GHz 1.0GHz COM-NO COM-NC Frequency NOTES 1. Coil operating power Pure DC current should be applied to the coil. The wave form should be rectangu- lar. If it includes ripple, the ripple factor should be less than 5%. However, check it with the actual circuit since the characteristics may be slightly different. The nominal operating voltage should be applied to the coil for more than 10 ms to set/reset the latching type relay. 2. Coil connection When connecting coils, refer to the wiring diagram to prevent mis-operation or mal- function. 3. External magnetic field Since RA relays are highly sensitive po- larized relays, their characteristics will be affected by a strong external magnetic field. Avoid using the relay under that condition. 4. Cleaning For automatic cleaning, the boiling meth- od is recommended. Avoid ultrasonic cleaning which subjects the relays to high frequency vibrations, which may cause the contacts to stick. It is recommended that alcoholic solvents be used. 5. Soldering Manual soldering shall be performed un- der following condition. Tip temperature: 280°C to 300°C .536°F to 572°F Wattage: 30 to 60W Soldering time: within 5s In case of automatic soldering, the follow- ing conditions should be observed 1) Position of measuring temperature 2) IR (infrared reflow) soldering method Temperature rise of relay itself may vary according to the mounting level or the heating method of reflow equipment. Therefore, please set the temperature of soldering portion of relay terminal and the top surface of the relay case not to exceed the above mentioned soldering condition. It is recommended to check the tempera- ture rise of each portion under actual mounting condition before use. The soldering earth shall be performed by manual soldering. B 1.0mm .039inch A: Surface of PC board where relay is mounted. B: Above the PC board surface. A T1 T2 T3 T4 T5 t1 t3 t4 t5 t2 A: B: t2 - t1 = 80 to 120 s t5 - t3 = 30 to 40 s t4 = 170 to 190 s T1=150 °C 302°F T2=160 °C 320°F T3=183 °C 361°F T4=245 °C 473°F T5=270 °C 518°F For Cautions for Use, see Relay Technical Information (Page 48 to 76). 9/1/2000 All Rights Reserved, © Copyright Matsushita Electric Works, Ltd.
