IRM-H538/TR2 The Notice of Application: Transmission remote control signal consist of four parts: Encode Part, IR Transmitter Source, IRM device, Decode Part 1. When IRM-H538 code select frequency, it need to well understand the center system of encode part. 2. Strong or weak light of IR Transmitter can affect distance of transmission. 3. Minimum Burst Length Tburst (number of pulses per burst) : 10 cycles 4. It needs to ensure the translation range of decode part if it is applied to the pulse-width range. If the above items hardly assure of its application, it’ll cause NG(no good) message from the edge of signal. Test Method： ： The specified electro-optical characteristics is satisfied under the following Conditions at the controllable distance. Measurement place A place that is nothing of extreme light reflected in the room. External light Project the light of ordinary white fluorescent lamps which are not high Frequency lamps and must be less then 10 Lux at the module surface. (Ee≦10Lux) Standard transmitter A transmitter whose output is so adjusted as to Vo=400mVp-p and the output Wave form shown in Fig.-1.According to the measurement method shown in Fig.-2 the standard transmitter is specified. However , the infrared photodiode to be used for the transmitter should be λp=940nm,∆λ=50nm. Also, photodiode is used of PD438B(Vr=5V). (Standard light / Light source temperature 2856°K). Measuring system According to the measuring system shown in Fig.-3 Fig.-1 Transmitter Wave Form D.U.T output Pulse Carrier frequency is adjusted to center frequency of each product.

IRM-H538/TR2 Recommended method of storage Dry box storage is recommended as soon as the aluminum bag has been opened prevent moisture absorption. The following conditions should be observed, if dry boxes are not available: Storage temperature 10℃ to 30℃ Storage humidity ≦60%RH max. After more than 72 hours under these conditions moisture content will be too high for Reflow soldering: In case of moisture absorption, the devices will recover to former condition by drying under the following condition: 192 hours at 40℃+5℃/-0℃ and 5%RH (dry air / nitrogen) or 96 hours at 60℃+5℃ and < 5%RH for all device containers or 24 hours at 125℃+5℃ not suitable for reel or tubes. ESD Precaution Proper storage and handing procedures should be followed to prevent ESD damage to the devices especially when they are removed from the Anti-static bag. Electro-Static Sensitive Devices warning labels are on the packing. Recommended Solder Profile 260°C Max. 10sec Max. 1~5°C/sec 1~5°C/sec. Pre-heating 180~200°C 60sec. Max. Above. 220°C 120sec.Max. Notice: (1) Reflow soldering should not be done more than two times. (2) When soldering, do not put stress on the IRM-H538/TR1 Series devices during heating.

IRM-H538/TR2 Soldering Iron Each terminal is to go to the tip of soldering iron temperature less than 350℃ for 3 seconds within once in less than the soldering iron capacity 25W. Leave two seconds and more intervals, and do soldering of each terminal. Be careful because the damage of the product is often started at the time of the hand solder. Repairing Repair should not be done after the Devices have been soldered. When repairing is unavoidable, a double-head soldering iron should be used (as below figure). It should be confirmed beforehand whether the characteristics of the Devices will or will not be damaged by repairing.
