I have in it the ST BAL-NRF01D3, with a 0.8pF capacitor.
In the forum I read in a post that some versions of the nRF51822 are not compatible with the BAL-NRF01D3, but with the BALF-NRF01D3. In the BAL-NRF01D3</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Mon, 30 Nov 2015 15:50:21 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/10534/balun-compatibility" /><item><title>RE: Balun compatibility</title><link>https://devzone.nordicsemi.com/thread/39195?ContentTypeID=1</link><pubDate>Mon, 30 Nov 2015 15:50:21 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:e7fa59c5-9912-431e-9fdc-35bcf1f0fb6e</guid><dc:creator>Daniel</dc:creator><description>&lt;p&gt;I have already done The board.

Thank you very much.

I cannot really guarantee anything though since we do not list it. But if ST states that it is compatible, it should work. Have you already created the boards, or are you still in the design phase?&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Balun compatibility</title><link>https://devzone.nordicsemi.com/thread/39194?ContentTypeID=1</link><pubDate>Mon, 30 Nov 2015 13:13:56 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:427ecdb7-d053-49e7-8a9a-9fd7c048941e</guid><dc:creator>Daniel</dc:creator><description>&lt;p&gt;So, anyway, I guest that I will have better results with the BALF-NRF01E3, but I can still use the BAL-NRF01E3.

&lt;p&gt;Can you link the forum post you refer to?&lt;/p&gt;
&lt;p&gt;We have a &lt;a href="https://www.nordicsemi.com/eng/Products/Bluetooth-Smart-Bluetooth-low-energy/nRF51822#3partyhw"&gt;list&lt;/a&gt; of supported BALUN&amp;#39;s on our website. According to this, you should use the &lt;a href="http://www.st.com/web/catalog/sense_power/FM139/CL1806/SC1508/PF261169"&gt;BALF-NRF01E3&lt;/a&gt; for best results.&lt;/p&gt;
&lt;p&gt;The &lt;a href="http://www.st.com/web/catalog/sense_power/FM139/CL1806/SC1508/PF260327?s_searchtype=partnumber"&gt;BALF-NRF01D3&lt;/a&gt; should work as well. I do not know why the documentation on ST&amp;#39;s site is as it is. My guess is that the BALF version came later, and support the same devices.&lt;/p&gt;
&lt;p&gt;The build codes describes what hardware version your chip is. The difference between hardware versions can be small fixes, or bigger changes. The big changes represent chip revisions. We have three revisions of the nRF51822.
In page 5 of our &lt;a href="http://infocenter.nordicsemi.com/pdf/nRF51_Series_Compatibility_Matrix_v2.5.pdf"&gt;compatibility matrix&lt;/a&gt;, you can find an overview of chip revisions, build codes and their compatibilities.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
